What BloomRPC Extended is

BloomRPC Extended is a free desktop GUI client for exploring and querying gRPC services on Linux, macOS, and Windows. The project is a maintained fork of the original BloomRPC, which it says was archived in January 2023. It supports native unary, server-streaming, client-streaming, and bidirectional calls, as well as gRPC-Web and server reflection. Users can import and manage .proto files, set up environments, edit metadata, and connect using TLS or SSL. The interface includes draggable tabs for services, search and filtering, service grouping, an overflow menu, and a close-all control. The project says packaged builds use CodeMirror 6 for syntax highlighting. Downloads are listed as macOS DMG, Windows EXE, and Linux AppImage or DEB. Homebrew installation instructions are provided for macOS and Scoop instructions for Windows, alongside GitHub releases. The repository links to GitHub Issues for problem reports and lists the license as LGPL-3.0-or-later. Building from source requires Bun v1.0 or later.
